Statistical Properties of Cold Streams In Massive Star-Forming Halos in TNG50

Isabel Medlock, Daisuke Nagai, Nir Mandelker +4

Cold, dense streams of gas are predicted to penetrate deeply into massive halos (> 10^12 Msun) at cosmic noon (z=4-2), fueling galaxies to sustain high star formation rates. We inv…

Merger-Driven Turbulence and Coherent Transport in the Intracluster Medium

Yiwei Zhang, Xun Shi, Daisuke Nagai

The distribution of metals and temperature in the intracluster medium (ICM) provides key insights into galaxy cluster evolution, revealing information about chemical enrichment and…

Automatic Machine Learning Framework to Study Morphological Parameters of AGN Host Galaxies within in the Hyper Supreme-Cam Wide Survey

Chuan Tian, C. Megan Urry, Aritra Ghosh +8

We present a composite machine learning framework to estimate posterior probability distributions of bulge-to-total light ratio, half-light radius, and flux for Active Galactic Nuc…

Denser Environments Cultivate Larger Galaxies: A Comprehensive Study beyond the Local Universe with 3 Million Hyper Suprime-Cam Galaxies

Aritra Ghosh, C. Megan Urry, Meredith C. Powell +5

The relationship between galaxy size and environment has remained enigmatic, with over a decade of conflicting results. We present one of the first comprehensive studies of the var…

A Differentiable Model of the Evolution of Dark Matter Halo Concentration

Dash Stevanovich, Andrew P. Hearin, Daisuke Nagai

We introduce a new model of the evolution of the concentration of dark matter halos, c(t). For individual halos, our model approximates c(t) as a power law with a time-dependent in…

Formation of dense filaments induced by runaway supermassive black holes

Go Ogiya, Daisuke Nagai

A narrow linear object extending from the centre of a galaxy at redshift has recently been discovered and interpreted as shocked gas filament formi…

The relation between gas density and velocity power spectra in galaxy clusters: qualitative treatment and cosmological simulations

I. Zhuravleva, E. Churazov, A. A. Schekochihin +6

We address the problem of evaluating the power spectrum of the velocity field of the ICM using only information on the plasma density fluctuations, which can be measured today by C…
